Title: Element-wire insulated conductor manufacture
Inventor: TAKESHITA FUMIO
IPC: H01B13/16
Filed: 1989-11-30
Abstract: PURPOSE:To prevent the formation of a partly poor oxide film on the surface of each of copper element-wires so as to form a uniform oxide film all over the length of the copper twisted element-wire conductor by heating a copper twisted element-wire conductor and then bringing it into contact with an oxidizing reaction gas of a temperature higher than its temperature to form an oxide film on its surface at a point of the time when its temperature rise rate becomes steady. CONSTITUTION:When a copper conductor is started to be brought into contact with an oxidizing reaction gas in such a condition that the temperature rise rate of the conductor does not reach its steadiness, copper hydroxide may be generated because the conductor temperature is too low to sufficiently advance the film-forming reaction of copper oxide. In order to satisfactorily advance the oxidizing reaction, a preferable gas contact start temperature of the conductor is specified to range from 30 deg.C to 35 deg.C. When the copper twisted element-wire conductor is brought into contact with the oxidizing reaction gas to form an oxide film, it is brought into contact with the oxidizing reaction gas in such a condition that the temperature rise rate of the copper twisted element-wire conductor itself becomes steady. The oxidizing reaction of the surface of each of copper element-wires may thus be advanced quickly to satisfactorily form the copper oxide film.

Title: Formation of semiconductor element isolation region
Inventor: AOKI KENJI
IPC: H01L21/76
Filed: 1989-12-01
Abstract: PURPOSE:To prevent an element region from being contaminated with impurity by a method wherein an impurity adsorption layer is formed on the active surface, from which an inert film on the surface of a semiconductor substrate is removed, of the substrate surface and after the impurities are diffused, an insulating layer is laminated to form a field doped layer and the laminated part of the insulating layer and the field doped layer is selectively removed to form the element region. CONSTITUTION:Gas containing impurity components is fed to an active surface, from which an inert film 2 on the surface of a semiconductor substrate 1 is removed, of the substrate surface to form an impurity feeding layer 3 and when a heat treatment is performed, the impurities are diffused and the layer 3 is turned into an impurity diffused layer 4. When an insulating film 5 is deposited on this layer, the high- concentration impurity layer 4 takes the form of interposing on the interface between the film 5 and the substrate 1 and the layer 4 prevents a semiconductor layer in the vicinity of the interface from being inverted and becomes an effective field doped layer 6 to function so as to increase a threshold voltage. When the laminate of these layers 5 and 6 is selectively removed to form an element region, the element region becomes a semiconductor element region 7 having no contamination due to the impurities and a good semiconductor element isolation region is formed.

Title: Stationary reactive power compensator
Inventor: IROKAWA SHOICHI
IPC: H02J3/16
Filed: 1994-11-24
Abstract: PURPOSE: To realize stabilized operation constantly regardless of the number of operating units by altering the control constant of each unit depending on the total number of units to be operated. CONSTITUTION: Output from a divider 19 for determining the ratio of the total capacity QA of operating units to the total capacity QT of a transforming station is delivered to a multiplier 20 and a divider 21. The multiplier 20 multiplies the ratio by a product of a unit A and a slope reactance XSL 11 whereas the divider 21 divides the product of ΔV=V-Vref and a transient gain K by the ratio. Consequently, even when the output from the divider 19 is reduced by a factor of 2, the substantial slope reactance XSL is decreased by a factor of 2 through the multiplier 20 and since the value of KXSL is substantially invariant even if the transient gain K is doubled through the divider 21, stabilized operation can be ensured regardless of the number of operating units.

Title: Discharge device and picture image formation device provided with the device
Inventor: NAGASE TOSHIKI
IPC: B65H43/06
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to inform common users of a loading amount in a paper discharge part by counting pulse output number of a photosensor detecting the movement of a disklike member on a slit moving in the interlocking relationship with a detection lever rotated by a sheet material to be discharged itself as a loading amount. SOLUTION: Since a rotation angle of a detection lever is large and a rotation angle of a disklike member 27 is also large when a loading height of sheet materials into a paper discharge part 11 is low, the number of pulses generated by a photosensor increases. Moreover, since a rotation angle of the detection lever is small and a rotation angle of the disklike member 27 is also small when a loading height of sheet materials into the paper discharge part 11 is high, the number of pulses generated by the photosensor is small. It becomes possible to measure the number of pulses of a pulse signal generated by the photosensor when the lever rises or lowers when a sheet material passes and measure a loading amount of the sheet materials loaded in the paper discharge part 11.  Consequently, it is possible to provide users in common on a network with the information of loading amount of a paper discharge tray.

The 3-way cock is so changed over so as to supply a cleaning liquid from the original liquid supplying pipe 3 when the membranes are clogged. The cleaning liquid is discharged together with the deposits on the inside surfaces of the membranes from the discharge pipe 10.
